I replied that I put £50 on it in early December, and she was out of the water for most of the intervening period, thus using zero sparks. Not sure how so much electricity was used – I shall await the reply.
I called and they checked. My balance is £49.60! A slight glitch in the system. They are very nice people, and have said that they will plug Frank back in, now that he is back home at Berth H8.
